bracing members 5., The members 3, t are preferably parallel toeachother and constitute supports about which the film is wound spirallywhen to be treated or,dried. It will be understood that the form anddimen sions of the frame members and the material of which theyare' mademay, he such purposes for which-v the pansible rubber tube? seatedtherein and ex- :tending longitudinally thereof, the'ends of "the-tubebeing sealed so that said tube constitutes anelastic chamber extending1on The rubb'enof which j thistubeais made is preferably-' of a highdegree of-elasticity so that when inflated as hereinafter described itpand readilyunder the internal pressure and willyield :und'erie-xterna'lpressure,

thelatter of course being dependentupon the -degr'ec of compressionofithegasor fluid .in the tube; The elastic tube 7 may be secured inplace by any. suitable means, such fordnstance as cement applied betweenthe surface of the groove and. the part of the tube-"seated therein. 1 ar In 'order 'to inflate the elastic chambers I to any suitable source(not shown) of air,

gasor. fluid under pressure, said tube having branches '9, 9 connectedto the .elastic chambers, respe ':tively, each of the-said branchesbeing provided with a' sultable valve. 10, a by meansofwhich thefiowfrom the source v? ofp'ressure may be controlled and permittedtoenter 2 both,- chambers simultaneously, or

:her 'one independentlyof the other as may be desired; Each .elastic;;chamber is also provided with --a valve 11 means of whic '1 the airorgasin the chamber may'be permitted to leak therefrom when desired inorderto regulate the degree of compressibility" of the chamber.

Each of the members 3' may be provided with a plurality of spaced pins 3projecting laterallytherefrom and .spaced apart a distance slightlygreater than the width of the film strip so that when" the film is woundonthe formftheturnsof the strip may be passed between the pins toprevent the separate turns, from coming in contact with each other.

While I have shown both of the bearing members 3, 4 provided with theelasticchambered bearing surfaces, I desire it understood that I mayprovide but one of said members with such chamber-without departing fromthe spirit and scope of the.

invention. I

In use the invention as-above described is operated as follows: If adrystrip of film is to besubjectedto a fluid, the film while woundon theframe is first wound -about the frame on the bearing members in themanner shown in Fig. 1 of the drawing, and the elastic chambers beinginflated so that the film will'be held securely thereon with the runsout of contact with each other.

\Vhen subjected tothe fluidthe peculiarities of the film will cause itto expand so as to more or less loosely engage the elastic chambers onthe bear1n .members, and

under this condition'the chambers may be firrther' inflated so that thefilm will again properly engage the same. As the, film dries it may, asheretofore stated, shrink, which shrinkage willordinarily be compensatedfor by the compression of the elastic chambers, but should thisshrinkage cause the film to'too tightllyen'gage the bearing members thevalves 11 crime of them, may be opened so as to ermit-Fthe' air to leakfrom the chamber or chambers so that the.

pressure againstthe be reduced to the proper degree. If the film is wetand 1n its expanded condition when first wrapped about the form, uponshrinking. due to the drying, the chambers will collapse or becompressed, and if necessary the air may be permitted to leak therefrom,as above described, to maintain the proper pressure of the film againstthe chambers.

In the form shown in Figs. ,3.and 4 the invention is embodied in theform of a drum.

having heads 13, 13 connected by a center member 14, each head beingcircular in form and provided with a circumferential groove 15 in whichis seated an annular tube 16 of highly elastic rubber. Against thesetubes are. arranged a plurality of bearing bars or members 17 formed attheir ends with recessesylS seated over the tubes, said-bars beingsecured in position at their ends by loop members 18 surrounding ins 19secured to the inner faces of the heads said loops permitting inwardmovement of the which regulate the pressure of bars but limitingout-ward movement: Thev air is supplied to these tubes in substantiallythe samemanner as that heretofore described for the form of theinvention shown in.Figs. 1 and 2, that is by a tube 20 connected with asource of pressure and having branches 21,- 21 connected respectively tosaid. tubes and each provided with acontrolling valve 22. Each of thetubes 16 may also be provided with an exitvaive23. In this form of theinvention the operation is substantially the same as that described forthe form shown in- Figs. '1 and 2, the film being wound on the bearingmembers in spiral form and kept slightly expanded by regulating thepressure in the air tubes members against the film.

In Fig. 5 the invention is shown as embodying a center member 24' fromtheop posite ends of which project .radially extending arms 25,corresponding arms being connected: by bearing members 26, there being aplurality of said members 26 lengthwise offeaeh arm, and said membersbeing arranged n splralrelation as shown. Each of the members 1s formedon itsouter. face the bearing with a groove 27, in which is seated aninflatable tube 28 extending longitudinally of In the formv of theinvention shown in Fig. 5 it'will be understood that the mem' bers 26aresuccessively placedin the carryingdram' composed of the members 25while the film is being wound, that is the innermost,.-m'embers 26 areinsertedgintlie frame and additional members 26 are in-v serted inthe'frame in spiral arrangement and succession while the film is beingwound; I desire it understood that any gas ,'or

fluid which will serve the purpose may beused for inflating the; cushionmembers, and I do not desire to be limited in any way by the use of theword air in the specification.

I claimz- :1. A rack or reel graphic film comprising" a frame havingfilm-receiving members upon which the.

film may be wound, one of said members be-,

ing provided with a hollow cushion 70f presenting a yield- 7 highlyelasmaterial ing-support to the film.

2. A rack or reel for supporting photq's hic film compri in a m hav-ingfor (supporting 'photo-- may be Wound, one of said members beingproyided with a cushion ofinflatable elastic material presenting ayielding support to the film.

3. A rack or reel for supporting photographic film comprising a framehaving film-receiving members upon which the film may be wound, one ofsaid members being provided with a'cushion of inflatable elasticmaterial presenting a yielding'support' to the film, and means for reulating the dey gree of inflationof said cus ion.
